What’s the wind got to do with it?

Arches National Canyon, Utah Formed when wind and water weather (erode) softer material first.

Ventifact on Mt. Falconer - Canada Wind carries fine particles that work like a sand blaster (i.e. sand, silt, clay, and ice particles)

Desert pavement Formed in arid environments when wind carries finer, more lightweight particles such as sand away. Large particles are left behind and protect from further erosion

Loess Deposits - Banks, Pennsylvania Yellowish, fine grained silt and clay sized particles formed by glaciers millions of years ago; carried and deposited by wind.

Sand Dunes leeward windward leeward Piles of sand deposited by wind - Leeward side has a steeper slope leeward windward leeward

Barchan dune east of Gilf Kebir Plateau Saudi Arabia Crescent shaped dunes formed from a unidirectional (one-direction) wind. Barchan dunes of the Namib Desert

Hueco Bolson Desert – Texas Ripple marks are miniature dunes within a dune (not more than 2 inches tall). Formed by cross winds and appear to be traveling in a different direction than the large dune.

Pedestal rock Africa Base of a rock is weathered and eroded more quickly due to sand blasting. Sand grains can only be picked up a couple of feet.
